When you or your staff spends their days using a vast array of different types of software that all require singing into in order for each user to access them, it can become very challenging to have to sign into each one individually. Rather than having to deal with entering user name and password for each program, single sign on authentication takes away the hassle.
With single sign on authentication each person can be equipped with an RSA token that once plugged into a USB port will let them access all software and databases that they have authority to access. Once the token is removed, the security is restored to keep those without the proper authentication from accessing these areas. One specific advantage to this is that each employee will be able to access the information and software they need from any computer terminal in the office.
